Climategate may be just the tip of the global-warming iceberg according to the Washington, D.C.-based Competitive Enterprise Institute, which says the next weather-science scandal may erupt right here in the United States.

For nearly three years CEI, a free-market, public-interest organization, has pursued a series of Freedom of Information Act Requests intended to force NASA's climate-science division to hand over e-mails it says could reflect the same sort of pro-warming bias seen in the recent e-mails from the Climatic Research Unit (CRU) of East Anglia University.

One reason NASA's unresponsiveness is drawing attention: For years, the CRU stonewalled a request filed through the British information-act process, before information was "hacked" and posted on the Internet in November.

"They have resisted and haven't wanted to turn anything over," CEI Energy and Global Warming Policy Director Myron Ebell says of NASA. "… So this looks like climate gate all over again to us."
